    Abstract: An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

    Abstract: An optical mechanism installed in an office machine, which has a machine base defining an internal space, and a paper-feeding mechanism arranged on the machine base, the paper-feeding mechanism having an inside receiving space and a bottom incident zone for the passing of light. The optical mechanism has an optical-path device formed of an image sensor and an optical module and mounted in the internal space inside the machine base, and a light-focusing structure mounted in the receiving space inside the paper-feeding mechanism above the incident zone for increasing optical path.

    Abstract: An image reading apparatus in which extended image reading time is prevented when high quality image data is obtained, which image data is corrected by invisible light such as infrared light which is transmitted through an original. In a CCD scanner, visible light emitted from a light source is irradiated onto a photographic film. Infrared light emitted from the light source is reduced by an IR light reducing filter to be irradiated onto the photographic film. Visible light which has been transmitted through the photographic film is irradiated on a linear CCD by a lens unit, and the infrared light is reflected by a dichroic mirror to be irradiated on the linear CCD. Accordingly, the reading of invisible light can be effected at the same time that the reading of visible light is effected. It is therefore possible to prevent image reading time from becoming long due to the time required for the receiving of invisible light.

    Abstract: An image reading apparatus comprises: a light source for irradiating light to a photographic photosensitive material; an image forming optical system for forming reflected or transmitted light emitted from a photosensitive film into an image; a film carrier having a shape correspomding to various types of photographic films to be loaded from the outside and supporting the photosensitive film; and an optical waveguide being replaceably attached to a predetermined reference attachment position and having a shape corresponding to the type of photographic film. Furthermore, there are provided a withdrawing mechanism for moving the optical waveguide from the reference attachment position in the case of an incorrect combination of the shape of the film carrier and the shape of the optical waveguide, and a detecting mechanism therefor.
